This is a Low-power FM stereo radio receiver module found in many portable media players. Based on the TEA5767 IC from Philips, the FM receiver uses a simple command set over an I2C or SPI interface. The radio is completely adjustment-free and only requires a minimum of small and low cost external components. The radio can be tuned to the European, US, and Japanese FM bands.
Crystal and supporting components are all on board, all you need to attach is an antenna!
